ALBERT H. HEWITT, OF BATAVIA, NEW YORK.

IMPROVEMENT IN ATTACHMENTS FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 121,366, dated November 28, 1871.

To all whom t may concer-n:

Be it known that I, ALBERT H. HEWITT, of Batavia, in the county of Genesee and State of New York, have invented a new and Improved Cloth and Trimming-Guide 5 and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the saine, reference being had to the accompanying drawing forming part of this specification.

This invention relates to improvements in guides for sewing-machines; and it consists in the arrangement of devices, hereinafter described, whereby a gauge is provided by which lace or other trimming may be stitched on the cloth at the same time it is hemmed, and on the wrong side.

Figure l is a plan view of my improved guide, and a hemmer and presser of a sewing-machine. Fig. 2 is a side elevation of Fig. l, and Fig. Sis a section on the line x x of Fig. l.

Similar letters of reference indicate corresponding parts.

A is an ordinary cloth-gauge, attached to the plate B, by which it is clamped to the machine in the usual way. G is a hemmer, and H a presser This gauge is provided with three holes, a b e, for the projecting tongues e f g of a plate, D, fitted to slide forward and back on the top of B, and to be held in any position by. the set-screw which holds plate B; or it may be by another screwing' into B. The tongue c is preferably wider than the others, and projects not quite as far as the tongue f, and rests against the side of the presser, while tongue g projects alittle more than f. It is also in a higher plane than the others, and rounded or curved on the upper surface, while tongue f is curved on the lower side to facilitate the passage of the trimming. Said tongue g holds the trimming up so as not to hide the hemmer from view.

This gauge is placed on the machine at the same time the hemmer is used, so that part A will cause the edge of the trimming E to be stitched on to the cloth to run under the needle properly. The plate D is then set so that tongue f will project about as far as the side of the hemmer; the trimming is then put in over tongue g, and under tongues f and e, as clearly shown in Fig. 1, so as to pass close alongside of and gradually work sufciently under the hemmer to have the piece of the cloth F turned over-it, as shown best in Fig. 3.

The guide A sh'ould be made to curve away to the right at the front, so that the trimming will run around said bend in feeding in from a position at one side where it may be kept free from the cloth; but it will work well without being so curved, and with little or no attention from the operator, thereby leaving the hands at liberty to guide the article being hemmed.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The slide-plate D having tongue e adapted to bear against the presser-foot, the longer tongue j' curved on its lower side and projecting as far as the side of the hemmer, and the longest tongue g curved on its upper surface, in a higher plane than the others, and receiving the trimming between it and the other tongue, the thus-constructed plate and tongues being combined with a clothgauge, A B, having' the holes a b c, as and for the purpose specified.

A. H. HEWITT.
